Microcystic Adnexal Carcinoma under the Microscope

Microcystic Adnexal Carcinoma (MAC) is an uncommon, locally aggressive malignant appendage tumor commonly classified as a low-grade sweat gland carcinoma. The tumor usually occurs on the head and neck, particularly the central face. Microcystic adnexal carcinoma shows aggressive local invasion but has little metastatic potential. If MAC is diagnosed too late, it can be inoperable because of its infiltrative growth.
